Doesn’t really matter, you’ll be doing <30 most of the time anyway 😉
My cheap £25 tyres (came on the car) literally disintegrated on me – carcass bulged creating slight eggs (almost un-noticeable without taking the wheels off and giving them a good look over, I did try to figure out why I had a slight wobble on the steering by jacking it up and spinning them, it wasn’t obvious) which caused serious grip issues and within a hundred miles or so the rubber parted company with the fabric.
All of my local tyre places automatically jump to the cheapest possible tyre for the size you select. “I want a decent mid-range tyre” – we have Barum’s for £28 each, they’re made from the same moulds as bobs third sisters favourite tyre similar to those Michelins over there – all the taxi drivers love them. Great, I’ll take something else, thanks!
